Common questions about the Cartier Tank Must WSTA0040

How big is the Cartier Tank Must WSTA0040?

The case measures 41mm long and 31mm wide, and 8.4mm thick. Case material: Stainless steel. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

What movement is in the WSTA0040?

Automatic, Cal. 1847 MC. Power reserve is 40 hours.

Is the WSTA0040 water resistant?

It is rated to 30 meters, about 98 feet. That covers rain and hand washing. It is not rated for swimming. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

When was the Cartier Tank Must WSTA0040 made?

Cartier produced this reference from 2021 to the present day. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.
